Although it does require discipline and daily application, it offers
you the chance to learn modern harmony many times faster than
previously possible.
It may seem overly involved to think through four steps to play a
chord.
As a beginning student, you may try to learn chords visually without
the necessary intellectual control. However, don't forget that there
are hundreds of chords.
If you want to move really fast, you must be organized.
The most important thing of all, besides the intellectual control that
these four steps give you, is that you learn to think of the notes of
a chord in terms of numbers: root, 3rd, 5th, 7th. This is the
professional approach.
The opposite approach, thinking of the notes in terms of their letter
names, C, E, G, B will give you an amateurish, inefficient control of
the keyboard, even after years of effort.
This approach to chord construction is really a "slow motion" insight
into the type of thought a professional keyboard artist uses
automatically.
